Paper Abstract

Digital holography is one of the most promising tool for industrial applications. Over a period of years a number of effective compensating techniques have been developed. In this paper compensation and comparative techniques will be summarized to develop more intelligent measuring systems. Digital holography is an excellent tool for comparative measurement. Using this technique remote measurement is also can be done, because the real or simulated digital holograms of the master object can be transferred via Internet. We present a new measurement setup, combining two out-of-plane displacement measurements with different sensitivities and an adaptive compensation method. Using this method we can produce much more precise displacement map, than it would be possible by a single measurement.
